In addition describe a kind of can the exemplary implementation of exhaust-driven turbo-charger that runs of motor type and generator-type.
Shortcoming for the aforesaid way of the energy regeneration of the exhaust-driven turbo-charger auxiliary by means of electricity motor is, these modes however can not be applied on pure engine-driven (verbrennungsmotorischangetriebene) motor vehicle or require to provide extra energy storage.
Summary of the invention
Therefore, it is an object of the present invention to provide a kind of method of improvement for running the auxiliary exhaust-driven turbo-charger of electricity motor and device, the shortcoming of routine techniques can be avoided with it. The object of the present invention is especially, the operation method of a kind of exhaust-driven turbo-charger auxiliary for electricity motor is provided, utilize its in the running status with sufficient exhaust energy by the generator-type of electricity motor run renewable part exhaust energy and its in the situation of pure engine-driven motor vehicle, that is in the situation of the vehicle without mixed drive chain equally can simpler and more cost-effective design and be employed.
These objects are realized by a kind of method with the feature of main claim. In addition, these objects are realized by a kind of device with the feature of claim arranged side by side. The favourable enforcement mode of the present invention and application are the objects of dependent claims and are described further with reference to when accompanying drawing in part in the following description.
According to the method that invention proposes the auxiliary exhaust-driven turbo-charger of a kind of electric motor for running motor vehicle, especially commercial car, it is included in the first operational mode that wherein exhaust-driven turbo-charger electricity motor is auxiliarily driven, and wherein exhaust-driven turbo-charger by the 2nd operational mode of regenerative electric energy in exhaust energy. Motor vehicle is preferably without engine-driven motor vehicle or the light hybrid vehicle (Mildhybridfahrzeug) of combination drive device, and motor can reduce and can partially recycled braking energy in the generator-type of motor is run for power ascension and for consuming by jack engine in motor type runs wherein.
Total viewpoint according to the present invention, in the first operational mode, electric energy is by the low pressure In-vehicle networking (Niederspannungsbordnetz of motor vehicle, or claim low pressure automobile circuit) conveying is to exhaust-driven turbo-charger, and the electric energy regenerated by exhaust-driven turbo-charger in the 2nd operational mode (ohnevorherigeZwischenspeicherung) in the situation that nothing is temporary in advance is transfused in low pressure In-vehicle networking.
So the present invention comprises technology instruction total as follows, namely, the low pressure In-vehicle networking of the existing routine of motor vehicle is used to be provided for the electric energy of exhaust-driven turbo-charger and is used to hold the electric energy of the regeneration of exhaust-driven turbo-charger, thus does not link the extra high voltage network with electric high-voltage reservoir or other extra current condenser. Low pressure In-vehicle networking (is also referred to as low voltage or NV In-vehicle networking) and is understood to the small voltage In-vehicle networking of the routine of motor vehicle, it is with until the voltage rating of 60V is run, such as car 12V, for commercial car 24V's or for the voltage rating of power truck or the 48V of motor vehicle driven by mixed power.

Then, exhaust-gas mixture flows out in gas barrier via turbine outlet 6b. Turbine 12 is connected with compressor 11 by axle 13. This compressor is given by fresh air conveying via compressor entrance 7b. Forced air (Ladeluft) to be delivered to oil engine 2 is compressed and thus promotes the power (Leistung) of oil engine 2 by compressor 11. The forced air compressed by compressor 11 is carried to charge air cooler 8 via charge air duct 7a and is then transfused in oil engine 2.
ATL10 is implemented as the auxiliary exhaust-driven turbo-charger of electricity motor. For this reason, ATL10 be provided with can the motor 14 that runs of motor type and generator-type, it can connect with drive shaft 13 in the way of transmitting moment of torsion or connect and arrange the driving of other parts 11 to 13 for exhaust-driven turbo-charger or driving is assisted.
The electricity motor type of motor 14 and the operation of generator-type are controlled by operating device 1.In addition, operating device 1 arranges the operation for the alternator 3 in the 24V low pressure In-vehicle networking controlling to be arranged in vehicle. Alternator 3 can connect or connect with bent axle in the way of transmitting moment of torsion, at this such as via belt transmission 4. Operating device 1 especially arrange be used for can selection of land motor type or generator-type ground run alternator 3, wherein, alternator 3 routine generator-type run in drive by oil engine 2. At this, the electric current produced can be fed to the starting engine battery (Starterbatterie) 5 being arranged in low pressure In-vehicle networking, and this is illustrated by electrical lead 15. Other electric load in low pressure In-vehicle networking (not corresponding illustrate) can be powered by alternator 3 and starting engine battery 5 in known manner. In addition, the electric current produced in generator-type is run can be fed to the motor 14 of ATL10 via operating device 1, and for running with making its motor type, this carrys out graphic extension by electrical lead 9.
Feature according to the teachings of the present invention is, alternator 3 can be run by operating device 1 motor type equally. In this operational mode, the electric energy (when it runs in regeneration runs) produced by the motor 14 of ATL10 is fed to alternator 3. Depending on the operational mode (that is generator-type or motor type) of ATL10, the direction of the energy transmission between the motor 14 and alternator 3 of ATL10 changes, and this is illustrated by double-headed arrow 9.
In addition, operating device 1 arrange be used for when needed equally can between the motor 14 of ATL10 and starting engine battery 5 transmitted in both directions energy, such as in the situation of the starting engine battery 5 discharged in its process of charging pilot alternator 3.

In step sl, the current running status of vehicle determined continuously by operating device 1. Current running status can such as be determined according to the current rotating speed of oil engine 2, current required motor torque and/or current supercharging pressure.
Depend on determined running status, determine with which kind of operational mode to run the motor 14 of ATL10 in step s 2 by operating device.
If vehicle is at full capacity or in high loading operation, so operating device 1 so manipulates motor 14 in step s 4 which, namely so that its generator-type ground runs and ATL10 runs in regeneration operation. It is such as those operation points irised out by the line indicated with Reference numeral 30 in figure 3 in the running status at full capacity or in high loading operation. At this, Fig. 3 shows motor operation characteristic curve race, its with depend on the current moment of torsion of motor rotary speed form so that motor operation state to be described. At this, solid line 31 describes the boundary curve in situation at full capacity, is also exactly the moment of torsion of the maximum possible of oil engine 2 under the given motor rotary speed of oil engine 2 in situation at full capacity. In addition, the main running region often occurred in time is indicated in figure 3 by circular lines 32.At this, depend on design and running and it is also feasible that, also regenerate even if utilizing than power less at full capacity. Common purpose of design is the expansion wide as far as possible of the regeneration zone in motor operation characteristic curve race. Part load regeneration equally can, consider parameters of hydraulic motor when, force to carry out by the setter (exhaust gas recirculation, variable turbine geometrical shape, exhaust valve) at motor place.
As previously mentioned like that, the energy regenerated by ATL10 directly is carried to low pressure In-vehicle networking via the power electric device of operating device in without the situation of working storage, such as run alternator 3 for electricity motor type, thus, oil engine 2 can be assisted.
If the transient operating condition of oil engine 2 is identified (such as starting process or shift process), so exhaust-driven turbo-charger electricity motor auxiliarily runs (step S3).
